在Android 5.1中安装apk时出错？

Question

我在Android 5.1中安装apk时遇到错误。

Package couldn't be installed in /data/app/com.acelrtech.apps.xxxxxxxxx-1
                                               com.android.server.pm.PackageManagerException: scanPackageLI

这是Gradle的主要部分看起来像。希望有更好的投入。

compileSdkVersion 23
buildToolsVersion '23.0.3'
        
defaultConfig {
            
applicationId "com.acelrtech.apps.xxxxxxxxxxxx”
               
minSdkVersion 14
           
targetSdkVersion 21
            
versionCode 23
             
versionName "2016.6.21"
            
generatedDensities = []
            
multiDexEnabled true
        }

我也试过这个solution ..
